Cenozoic Glacial History of the Lambert Graben-Prydz Bay Region, East Antarctica

At least 10 intervals of glacial advance and more than 17 intervals of glacial retreat are recorded in the glacigene strata of the Prydz Bay-Lambert Graben region. This review from Geoscience Australia presents a partial reconstruction of Cenozoic glacial extent, comparing it to eustatic sea-level records from the southern Australian margin. The data was last updated on 2026-04-20.

Use Cases

• Reconstructing paleo-glacial extent based on described intervals of advance and retreat.
• Correlating Antarctic glacial cycles with eustatic sea-level records from other regions.
• Modeling past marine incursions using the described >450 km inland reach during extreme retreats.
• Analyzing continental shelf progradation linked to large advances of the Lambert Glacier.

Strengths

• Describes a specific, quantified glacial history with at least 10 advance and 17 retreat intervals.
• Provides a spatial context with events reaching >450 km inland from the modern ice shelf edge.
• Compares regional glacial history to external eustatic sea-level records.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The description notes the stratigraphic record is incomplete, with fewer glacial cycles recorded than expected from Milankovitch frequencies.
• Freshness should be verified as the last update date is 2026-04-20.
